Can I use the I2C Module both as a master and slave at the same time. I need to do this on STM32F101VE.

I understand that in I2C slave cannot initiate a data transfer. I have a requirement for bidirectional communication where any of the nodes can initiate a data transfer. I dont want to impleent any kind of polling, this might consume MCU resources. Since the I2C is Multi Master capable, I plan to run both nodes as master and in this regard I want to know if I can run the MCU both Master and Slave at the same time.
